Health Benefits of Water Kefir

1. Probiotic Power

Water kefir contains multiple strains of beneficial bacteria and yeasts that can support digestive health and immunity.

2. Improved Digestion

Regular consumption may help ease bloating, irregularity, and indigestion.

3. Sugar Reduction

Though made with sugar, most of it is consumed during fermentation, resulting in a low-sugar final product.

4. Hydration with a Twist

Unlike many commercial sodas, water kefir hydrates with added functional benefits.

What You’ll Need to Get Started

Equipment:

• 1-litre wide-mouth glass jar
• Plastic or wooden spoon (no metal on grains)
• Fine mesh plastic strainer
• Muslin cloth or paper towel + rubber band
• Swing-top bottles for second ferment

Ingredients:

• 1 tablespoon water kefir grains
• 1 litre filtered, dechlorinated water
• 3 tablespoons white sugar (or organic cane sugar)
• Optional: pinch of baking soda or molasses (mineral boost)

Tip: Avoid metal utensils or lids—they can harm the kefir grains.

Water Kefir Fermentation

First Ferment (24–48 Hours)

1. Dissolve 3 tbsp sugar in 1 litre filtered water.
2. Add water kefir grains.
3. Optional: Add a slice of lemon or a dried fig (for flavour/minerals).
4. Cover with cloth and secure.
5. Leave at room temp (20–25°C) for 1–2 days.
6. Taste test: should be mildly sweet and slightly tangy.

Strain and Bottle

1. Strain liquid into another container using a plastic sieve.
2. Reserve grains for your next batch.
3. Pour liquid into flip-top bottles.

Second Ferment (Optional, 1–3 Days)

1. Add flavourings to bottles: fruit juice, herbs, dried fruit, etc.
2. Seal and leave at room temp to carbonate.
3. Chill and serve once desired fizz is achieved.

Note: Always open bottles slowly and over the sink. Pressure builds quickly!

Flavour Ideas for Second Fermentation

Fruity:

• Raspberry + lime
• Pineapple + mint
• Strawberry + basil

Citrus:

• Orange + ginger
• Lemon + lavender
• Grapefruit + rosemary

Spiced:

• Cinnamon + apple
• Cardamom + pear
• Clove + cranberry

Bonus Tip: Add flavour, ferment 2 days, then strain out solids before chilling.

How to Care for Your Kefir Grains

• Feed regularly: Every 24–48 hours
• Use mineral-rich sugar: Add molasses or a pinch of salt if needed
• Store grains: In sugar water in the fridge (for up to 3 weeks)
• Don’t freeze or expose to metal
